I'm not sure there's anything Amazon can really do. AFAIK, it's a script that just scrapes the information on a timer, like Internet Archive does. It's no different from checking it yourself and making a spreadsheet, right?
Depends. Amazon's terms and conditions for participation in their affiliate program explicitly states that doing that is breach. What they can do, and like I mentioned do do, is they close down your account and keep your money, and now you're out of business.
